This Physical science topic demonstrates my maximum understanding of physical science concepts because it reviews the information we learned in class about acids and bases. An acid is a material that can release a proton or hydrogen ion (H +). A base is a material that can donate a hydroxide ion (OH-). In this project “Self-inflating Balloons” I am trying to demonstrate how filling a balloon with baking soda and pouring it into a portion of vinegar will make a chemical reaction. When the two substances mix, you get carbonic acid, which is unstable, comes apart, and become carbon dioxide and water. Since the carbon dioxide is much less dense it inflates the balloon. The evidence presented to provide that I have progressed
in my understanding is when the reaction occurs and I see that the outcome has the right result which is the balloon inflating. The reason this topic is in my portfolio was to explain my understanding of acid and bases in an example of an experiment
